The current flu season has been especially hard on young adults and the middle-aged. A new report from the Centers for Disease Control shows people, ages 18 to 64, account for about 60 percent of all hospitalizations this season. Flu deaths are also up for this age group.
In Pennsylvania,the largest number of flu deaths, 21, has occurred in people 50 to 64. Seventeen people 65 and over have died of the flu in Pa.
According to the CDC, younger adults are the least likely to be vaccinated every year. Also, H1N1 is the predominant flu strain this season and it mostly affects younger people.
Doctors say it's not too late to get vaccinated. Government health officials say the shot is about 60 percent effective which is typical.
Researchers are working to find a universal flu shot that will provide long-term protection, so people won't have to get vaccinated every year.
